Subject: [PATCH 1/1] arm64: dts: meson-sm1-sei610: gpio-keys: switch to IRQs

From: Kevin Hilman <[email-masked]>
Date: Thu, 21 Nov 2019 10:37:11 -0800

From: Kevin Hilman <[email-masked]>

Switch the GPIO buttons/switches to use interrupts instead of polling.
While at it, add the mic mute switch and the power button.
